## Percentages Hint

Building blocks:

**50%** divide by 2

**25% **divide by 4 (half and half again)

**10%** divide by 10

**1%** divide by 100

Other percentages:

**2%** get 1%, then double it (or add 1% and 1%)

**20%** get 10%, then double it (or add 10% and 10%)

**5%** get 10%, then half it

**15%** get 10%, get 5% (by halving 10%) then add the 10% and the 5%

**30%** get 10% and times by 3 (or add 10%, 10% and 10%)

**33 1/3%** divide by 3

**75%** get 50% and 25% and add them

**40%** get 10% and times by 4

**90%** get 10% and take it away from 100% (100% is the number you start with)

**95%** get 5% (see above) and take it away from 100% (100% is the number you start with)

**110%** add 10% to 100% (100% is the number you start with)

**101%** add 1% to 100% (100% is the number you start with)

**150%** add 50% to 100% (100% is the number you start with)

**250%** add 100% (start number), 100% (start number) and 50%

## Religion and Ordering Numbers

**What religions are represented by the four symbols above?**

**Arrange the religions in order of how many followers you believe they have, from least to greatest**

**Research what the actual numbers of followers are for each religion and re-order**

**Extension: Choose one religion and consider where in the world it’s followers are concentrated. What other countries have a high proportion of that religion? What reasons can you give for the distribution of that religion?**
